RAILWAY CONSTRUCTION.

Specification of Letters Patent.

Patented Dec.1,1914.

Application filed February 20, 1914. Serial No. 819,905.

To all whom it may concern:

Be it known that I, RniMnR 1T. DITHMER, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Railway Construction, of which the following is a specification.

My invention relates to railway constructions, and the object of this improvement is to provide a simple and effective construction of the character mentioned in which an elongated block of concrete is disposed, longitudinally of the road-bed under each rail thereof, and means for removably securing the rail in position thereon.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a plan view of a section of railway construction embodying my invention, Fig. 2 is a section taken on line 22 in Fig. 1, Fig. 3 is a side elevation of one of the casting members embedded in the concrete blocks of the construction, Fig. 4c is a section of the same taken on line H in Fig. 8, Fig. 5 is a section taken on line 55 in Fig. 4-, Fig. 6 is a fragmental section taken on line 6-6 in Fig. 1, and Figs. 7 and 8 are side views of a bolt used in the construction.

The preferred form of construction as illustrated in the accompanying drawings comprises elongated concrete blocks 9 embedded in the road-bed 10. The concrete blocks 9 are disposed longitudinally of the road-bed under and adapted to support each of the rails of the track.

Embedded in each of the concreteblocks 9 are members 11, formed of cast iron or any other suitable substance, and to which the rail is secured. Each member 11 is preferably formed, as indicated, with a bottom plate 12, an upper open plate 13, ribs 14: and hollow portions 15. In said hollow portions 15 are provided perforations 16 each of which has a narrow groove at opposite sides thereof. At the bottom of each of the perforations 16 is an enlargement 17 and at the up er end of said enlargement 17 is a recess 18 orming a shoulder against which the head 19 of bolt 20 is adapted to rest in securing the rail to the supporting base. The head of bolt 20 is preferably of T-form with the ends of such head adapted to rest in the recesses 18 and the head being adapted to pass through the perforation 16. This construction is provided so that'any one of the bolts 20 may be removed from the construction when so desired without disturbing any of the other bolts. This is accomplished by loosening the nut 21. and turning the bolt through ninety degrees which brings the head 19 from a position registering with the recess 18 to a position registering with the narrow grooves at the sides of perforations 16 when the bolt maybe moved longitudinally out of theperforation 16, as will be readily understood.

Immediately on each block 9 is provided an elongated member 22, preferably formed of wood inv order to give the track the de sired resiliency. Above each member 9 and resting on a member 22 is a chair 23 adapted to receive the railway rail'2l. On the edges of the chairs 23 and flanges of rails 24- are flange holding jaws 25. Between the flanges of rails 24 and the under sides of jaws 25 are members 26 preferably of wood to increase the friction between the rail and holding jaw 25, and to permit slight resiliency to the construction. The chairs 23 and jaws 25 also are provided with perforations similar in cross section to the perforations 16 and registering therewith so that bolts 20 may be passed through them in the same manner that they are passed through said perforations 16.

At intervals along rails 24 are provided connecting rods 27 each provided with a connection engaging the outer edges of the flanges of rails 24 and provided with a turn-buckle therein in order to adjust the rods 27 to position. The connecting rods 27 and casting members 11 may be provided along the rails 24: as often as necessary and depend upon the sizes of the rails and sizes of the trains which pass over the tracks.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to. be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A railway construction comprising a concrete foundation block; a railway rail on said block; a metallic member embedded in said block, said member having a central vertical rib extending longitudinally of said rail and short vertical ribs extending laterally of said first mentioned rib; and ties tying said rail to said member, substantially as described.

2. A railway construction comprising a concrete foundation block; a railway rail above said block; a metallic member embedded in said block, there being a row of perforations in each lateral edge of said member, a rib positioned centrally between said rows of perforations and longitudinally of said rail and a rib extending laterally from said first mentioned rib to each of said perforations; and bolts through each of said perforations tying said rail to said block, substantially as described.

3. A railway construction comprising a concrete foundation block; a resilient member on said block; a railway rail above said member; a chair on said member and supporting said rail, there being upstanding edges 011 said chair fitting the lateral edges of and extending above the flanges of said rail; resilient members on the flanges of said rail and against the upstanding edges of said chair; jaws disposed on said last mentioned resilient members and reaching over said upstanding edges; and bolts through said jaws, chair and first mentioned resilient member and extending into said block, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
